Food and beverage manufacturers have to adhere to extremely high standards of production quality, both to meet their regulatory obligations and to manage risk when bringing a product to market. Sieving and sifting food powders is a critical step in the manufacturing of several products, one that is responsible for filtering out fine impurities that can ...

Maintaining sanitary conditions is an important priority in food and beverage, pharmaceutical and a number of other industry applications. If your operation requires sieving powders, the equipment you use to do this is a critical control point for preventing contamination. Don’t let an unsanitary ...

The Salsnes Technology has been developed to work as a stand alone unit or an addition to primary wastewater treatment facilities. The process incorporates an continuous mesh screen that uses air as backwash therefore producing a high dry solids content waste. The technology has been widely accepted in Europe and work is being done in North and South America including installations and pilot ...

Benthic macrofauna are used extensively for environmental assessment, but the area sampled and sieve sizes used to capture animals often differ among studies. Here, we sampled 80 sites using 3 different sized sampling areas (0.1, 0.05, 0.0071 m2) and sieved those sediments through each of 2 screen sizes (0.5, 1 mm) to evaluate their effect on number of individuals, number of species, dominance, ...

The objective of this study was to compare some basic characteristics of sludge from fine mesh sieves (sieve sludge) with sludge from primary clarifiers (primary sludge) regarding their energy potential with a focus on anaerobic digestion and/or incineration. Nineteen samples of sludge from fine mesh sieve plants (most of them without fine screens and grit chambers as pre-treatment) and 10 ...

The purpose of this project was to investigate the effect of selective particle removal during primary treatment on nitrogen removal in moving bed biofilm reactors (MBBRs). Two small MBBR pilot plants were operated in parallel, where one train treated 2 mm screened municipal wastewater and the other train treated wastewater that had passed through a Salsnes Filter SF1000 rotating belt sieve ...

Quickly and accurately screening silica sand is an important priority in a number of manufacturing processes. Your choice of screening machine will have a significant impact on the quality of product you deliver and, as a result, on your bottom line and long-term financial viability. There are a number of silica sand screening ...

Vibratory screeners come in a wide range of sizes and configurations to support a diverse set of applications. Choosing the right machine for your purposes can be a daunting task — particularly if you’re upgrading older equipment that has been used for years. Technology has changed considerably, and there’s a good chance what was best for ...

Location: Vancouver, B.C. Description: A biorecovery facility was seeking to use its product as animal feed supplement. The facility treats biodegradable wastes using an Autothermal Thermophilic Aerobic digestion (ATAD) process. The ETV verification program involved developing a sampling protocol followed by a sampling program that included extensive analytical testing ...

When manufacturing fine powder products, such as food additives, pharmaceuticals or industrial chemicals, several tools are available to help you produce a higher quality of product. You’ve already put time and effort into the development of quality assurance systems to meet your regulatory requirements — taking the next step requires an investment in the right equipment. ...

Tarmac is a leading supplier of aggregates, mortar, concrete blocks, asphalt and ready mixed concrete. The Tarmac Shireoak site north of Birmingham is a bunter sand deposit. Raw Material Analysis The material is spilt 50/50 between sand and gravel but the sand is very fine- typically 30% passes the 300mm sieve, 7% of the raw material is silt. Tonnage: 200,000 ...

Shale shaker for solids control are devices that remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since drilling fluids solids control is vital in keeping down costs associated with the drilling ...

Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

VSI Crusher for sale VSI crusher is designed by reputed German expert of Shibang and every index of VSI crusher is in world’s leading standard. Gulin VSI crusher incorporates three crushing types and it can be operated 720 hours continuously. Nowadays, VSI crusher has replace hammer crusher roller ...

There are various methods of separating solids from a suspension. These include filtration, centrifuging and drying. In most cases, further processing of the resulting products cannot be carried out directly. They have to be reduced to the right particle size by means of a mill. This can be done with a Gericke Nibbler, which shreds the filter cakes efficiently using a basket and screen assembly. ...

Due to the changes in restrictions and the increase in the cost of landfill, the Gypsum Industry is looking for an alternative to handle the estimated 300,000 tons of new build plasterboard waste generated every year. The traditional way of separating gypsum from its backing is to use hammer mills, in conjunction with sieves, which is costly and generates a lot of dust.Atritor offers reprocessing ...

Efficient sorting for sustainable recycling instead of just pure disposal. That is the motto for dealing with building waste. What do you understand by the expression building waste? This is a collective expression for the diverse types of waste that occur on building sites. This includes mixtures of mineral and non mineral materials (e.g. stone mixed with wood, sheets of ...

The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
